Ukrainian drone strikes on southern Russia killed a 9-year-old boy and set fire to a major oil terminal, officials said Saturday, the day after Moscow launched a massive aerial attack on its neighbor that Ukrainian President Volodymyr Zelensky said was one of the heaviest bombardments of the country’s energy sector in the nearly three-year war.

Ukrainian President Volodymyr Zelensky said Russia launched 93 missiles and 200 drones in one of its largest attacks on Ukraine’s energy system.

KYIV (Reuters) -Russia launched a large-scale missile attack on Ukrainian energy facilities during the morning rush hour on Friday, Kyiv said, while explosions were heard in the Black Sea port of Odesa and other cities in western Ukraine.

The strikes targeted sites in western Ukraine, damaging energy facilities in several regions, some seriously. Authorities in Ivano-Frankivsk said it was the worst attack on the region so far. Moscow said the attack was in response to a Ukrainian strike on a military airbase in south-west Russia using US-made missiles.
